In an embodiment, a conduit connector can comprise: a body comprising a box engagement region capable of engaging an opening in an enclosure and a spring configured to engage the connector and the enclosure. The box engagement region can have a root surface, a leading tab, and a follower tab wherein the root surface and leading tab can be located between a leading edge and a secondary edge. A leading tab perimeter edge and a follower tab perimeter edge define a tab perimeter diameter that is larger than an opening in the enclosure. When the leading tab is inserted into the enclosure the spring can be disposed to engage the secondary edge and the enclosure.

Conduit connector

Electrical conduit to junction box connection system

A clip-on electrical conduit connector is designed to clip onto conduit for connection to junction boxes. The connector incorporates a junction box engagement portion, a conduit engagement portion, and a conduit stop. The junction box engagement portion includes a pair of attachment prongs and a grip enhancing feature. The conduit engagement portion includes two sides formed with a base, a longitudinal locking projection, and a transverse locking feature. The longitudinal locking projection prevents the conduit from being unintentionally withdrawn from the conduit engagement portion. The transverse locking feature includes a transverse locking gap for preventing unintentional withdrawal of the conduit in a transverse direction from the conduit engagement portion. Prior to final installation, the conduit is forcibly inserted into the conduit engagement portion by squeezing the conduit through the transverse locking gap or by threading the conduit into the conduit engagement portion.

An electrical conduit to junction box connection system is designed connect conduit to junction boxes. The system incorporates a compression nut and a body. The body includes a box engagement region, a nut engagement region, and a conduit engagement region. The box engagement region includes a radially extending leading and follower tab, a root surface, a tab centering ledge, and a tab centering flank. The nut engagement region includes a nut engagement region thread that cooperates with the compression nut. The conduit engagement region includes a conduit compression system. During installation, the leading tab is inserted into the knockout. An edge of the knockout is positioned in contact with the root surface. The body is reoriented which positions the follower tab inside the junction box. The compression nut is manipulated to compress the junction box between the compression nut and the leading and follower tabs.

A connector for facilitating the connection of electrical conduit or cable to junction box, which is fashioned from a single piece of material, and features a saddle member and rolled throat that are integral parts of the connector. These integrated features simplify manufacturing and ultimate use of the disclosed connector.

Safety lock conduit connector

A snap-in locknut adapter is shown for connectors having a flange adjacent a threaded distal end to be inserted through an opening of predetermined diameter in a bulkhead. The adapter is to include a body with front and rear ends, an outer surface, and a hollow interior portion having internal threads corresponding to the threaded distal end of the connector. At least a portion of the outer surface of the body is to have an effective outer diameter less than the predetermined diameter of the opening. The adapter also includes a plurality of peripherally spaced, displaceable snap-lock members which extend outwardly from the outer surface of the body and have an effective outer diameter larger than the predetermined diameter of the opening. Once the displaceable snap-lock members are displaced inwardly and pushed through an opening in a bulkhead, they assume their original shape to thereby resist removal of the adapter from the opening. The adapter also preferably includes integrally formed areas which facilitate tightening of the adapter on the threaded distal end of the connector once the snap-lock members have been snapped through the opening. In this way, the adapter ensures that the connector is drawn into intimate contact with the bulkhead.

Snap-in locknut adapter for connectors

There is provided a strain-relief, liquid tight for connecting conduit or the like to a bulkhead such as an electrical box, with the connector having a body having front and rear portions, and a substantially hollow inner throughbore formed along a longitudinal axis thereof. The front portion of the connector body is adapted for attachment to a bulkhead. A flexible seal member is mounted at least partially within the hollow inner throughbore for receiving a conduit inserted therethrough, this seal member facilitating a substantially liquid tight seal about an inserted conduit during use. An at least partially hollow grip for selectively gripping the conduit is included, and a clamp nut is telescoped over the rear portion of the body for selective longitudinal adjustment therealong. The longitudinal adjustment of this clamp nut provides inward radial compression of the flexible grip about the conduit. In a preferred embodiment of the present invention, the grip member comprises a plurality of gripping fingers cantilevered from a ring-like base portion, and the seal member is at least partially disposed within the grip member. A cam surface is provided in the interior of the body, and a compression member on the clamp nut urges the gripping fingers against this cam surface thereby causing the fingers to be compressed radially inward. This results in the conduit being gripped and also enhances the sealing of the seal member about the conduit.
